This was a small quake on a smaller fault near the coast. The San Andreas Fault is 60 miles inland near San Bernardino. That’s where any big one will come from. The smaller faults can cause quakes up to 7, but the San Andreas can cause 8 or larger quakes. Use to live in L.A., Riverside, San Bernardino and San Jose (during the 1989 Loma Prieta quake). Now live in Sacramento.
I think the potential for real big issues with the San Andreas fault is on the northern end of it. Central CA and North of SF. Further north in Oregon/WA is subduction zone land. Cascadia subduction zone.. Capable of big league tsunamis...Bad juju.
